It seems like we're really on the subject of filesystems and related technology the past few days. We had an interview with the man behind BeServed, an item on WinFS' current status, and now we - possibly - have news on ZFS coming to Linux. Possibly, because it's all speculation from here on out.

Granted, it's not perfect, and there are some issues. But it's not the train wreck that people make it out to be.

If it was a train wreck, it wouldn't be in FreeBSD AT ALL
I will wait until things clear up though. At this moment using ZFS is simply not justified on my systems. But it will be a nice "toy" for me on the next release.
